In total it is estimated that there are around 100,000 cameras which in total scan 20 billion license plates per month.

Why is Flock a problem?

Poor Security

Flock safety devices have been proven to be insecure and subject to dozens of security exploits. Flock denies this is an issue stating that "vulnerabilities would not only require physical access to a device, but also require intimate knowledge of internal device hardware" while YouTuber and researcher Benn Jordan said "It's extraordinarily easy, like 12-year-olds could do it".

Privacy Issues

Flock violates citizens fourth amendment right to privacy. It indiscriminantly citizens regardless of their involvement in active investigations. It is practically impossible to drive around the city without your every move being tracked by this AI system.

False Identification

Officers have acted on faulty warrant identifications by flock cameras, putting innocent citizens in danger. For example, a man was falsely arrested in Seattle when his car was flagged by a flock camera because his son (who has the same name) had a felony warrant.

Cooperation with ICE

From April 2024 to early 2025 SFPD illegally (State law prohibits out of state sharing) shared camera access with police departments in Georgia and Texas who assisted in immigrations enforcement.
